In such a case, switch the filter off and change theaperture setting.• When shooting in the [ (Easy Recording) or n (Auto) programs on bright sunny days outdoors, thecamera may display “ND ON”/“ND OFF” repeatedly. In this case, it may be effective to switch to the Avrecording program and adjust the setting of the F number to between f/5.6 and f/11 (the shutter speed maybecome higher than usual).The camera sets the appropriate shutter speed automatically to give the correct exposure.
